Short summary and additional steps relevant to this thread: reported a blank blue desktop after closing an unknown process and logging off; correctly recommended using Safe Mode and checking system files. A blank, entirely empty desktop after login usually means the Windows shell (Explorer) did not start, the user profile is damaged, or a malicious process altered startup settings.

A quick, non-destructive recovery that often proves the cause is to open Task Manager (Ctrl+Alt+Del), choose File → New Task, and run explorer.exe. If the taskbar and icons return, the shell failed to auto-start and the issue is local to startup configuration rather than core system failure.

Steps to diagnose persistent problems (do these from Safe Mode or Recovery if normal boot fails):

  • Use Last Known Good Configuration or System Restore to roll back recent registry/startup changes.
  • Test with a new local user account: a working desktop there points to a corrupted user profile.
  • Inspect Winlogon settings in the registry at
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
    and verify the Shell and Userinit entries point to the default shell and userinit executable. Always export/backup the registry before editing.

Other useful checks: look in Event Viewer for shell/startup errors, run disk integrity checks, and scan with an up-to-date malware scanner (some malware replaces the shell or modifies Winlogon). If system files are suspected (as suggested), run the System File Checker or perform a repair install from XP media after backing up personal data. Note: F8 is the standard key for Advanced Boot Options (Safe Mode); F12 commonly opens a BIOS/boot device menu and is not required for Safe Mode.

Hi,
Have you tried starting in safe mode, tapping F8 after the first beep on boot-up. Start in safe mode with networking.
Sometimes, some of the windows protected files can be lost or changed. To detect any problems run the program “System File Checker” (SFC). Before you run it you should purge your PC’s cache:-

Go to “START”
Click “RUN”
Type or “copy and paste”.. sfc.exe /purgecache

Note:- the space after “exe”.

The “purgecache” in this command will empty the cache before you run the file checker. You should always purge the cache before scanning with the System File Checker (SFC). That way, you can be sure that system files are copied from your Windows installation media, and are not infected with malware or corrupted. After the cache has been purged, run System File Checker.

Go to “START”
Click “RUN”
Type or “copy and paste”… sfc.exe /scannow

Note:- the space after “exe”. You may be required to use your installation disk.

This could take a long time to complete, when finished, reboot and see if the problem still exists.

Just because you have a good virus detector and you scan your PC every day does not mean that your PC is clean. Even if your PC is clean, it can not hurt to check and rule out that problem. A very good site here is located at:-

If you have tried everything there and you are still having problems, then maybe a Windows repair is required. If you want to repair your installation with your Operating System disk, go to:-
